## Chapter Index

* [Offshore Operation](https://docs.deltaquad.com/tac/flight/advanced-flight/offshore-operations)

{% hint style="danger" %}
Advanced flight operations encompass **GPS-denied** environments, **manual flying**, and **offshore operations.** These scenarios require **skilled** **piloting** without GPS assistance and demand a deep understanding of the DeltaQuad Evo and its controls. Only experienced pilots should attempt these maneuvers, as they involve navigating without GPS, which can complicate situational awareness and precision. A deep understanding of the [**Flight** ](https://docs.deltaquad.com/tac/flight)chapter is essential for maintaining stability and control in challenging conditions. Always **prioritize** **safety** and preparedness in such operations.

The following parameters can be adjusted for special operations in **AMC Menu (Advanced Mode) -> Advanced ->** [**Parameters**](https://docs.deltaquad.com/tac/auterion-mission-control-amc-overview/amc-menu/advanced#parameters).

* MPC\_MAX\_HOVER\_T

**Default:** 90 **Max:** 150

The DeltaQuad Evo's default maximum hover time is 90 seconds, but this can be extended to a maximum of 150 seconds. After the timeout, the vehicle will automatically force-land at its current location. Adjusting this value may be necessary for offshore operations.

* COM\_WIND\_MAX

**Default:** 14 **Max:** -1 (off)

By default, the DeltaQuad Evo can tolerate a maximum windspeed of 14 m/s. This limit can be disabled if a mission must be completed regardless of wind conditions.

* COM\_WIND\_MAX\_ACT&#x20;

**Default**: Return **Optional**: Warning

The maximum windspeed action can be changed to a warning. By default, the vehicle will return if the windspeed exceeds the tolerance limits.

If arming without GPS is not possible, set the following parameter to **Allow arming without GPS**.

* COM\_ARM\_WO\_GPS
